Expanded hydrogen-powered buses planned for Frankfurt's public transportation fleet
In the bustling city of Wiesbaden, battery-operated electric buses have become the norm, with around 120 of them currently in operation. The ESWE transport company, which serves the city, has made a strategic shift away from hydrogen buses, operating only battery-powered electric buses and one electric articulated bus following the addition of the latter in March 2025.
This shift in focus on battery-electric buses can be attributed to several factors. For one, battery-electric buses are more economical to operate per kilometer compared to hydrogen buses, making them a more attractive choice for public transport fleets.
Moreover, the infrastructure needed for hydrogen fueling and associated maintenance is more expensive and complex than for electric buses, which limits broader deployment. The reliability of hydrogen buses has also been a concern for some transport companies, with Wiesbaden's ESWE finding that hydrogen technology did not suit their operational conditions.
These challenges, coupled with the prevalence of battery-electric buses in cities such as Darmstadt, Kassel, Offenbach, and Fulda, have made battery-electric technology the dominant choice in local public transport. In contrast, hydrogen buses are less common, with their use primarily limited to a few districts, including Frankfurt, Groß-Gerau, and Gießen.
While hydrogen buses are not a common sight in Wiesbaden, it's worth noting that they were previously in operation. However, they are no longer in service, with the ESWE transport company no longer operating hydrogen buses.
Elsewhere in Germany, there are ongoing projects focusing on green hydrogen production and refueling infrastructure, indicating a long-term strategic interest in hydrogen as an energy carrier. However, these are still in their early stages and require further development for widespread urban use.
In conclusion, the higher operational costs, expensive infrastructure, and maintenance challenges associated with hydrogen buses, as well as their questionable suitability for certain operational conditions, contribute to their limited use in Hessian cities. As technology advances and infrastructure improves, it is possible that hydrogen buses may become more common in the future.

In the context of the local public transportation industry, the financial advantages of battery-electric buses are significant, making them a preferred choice over hydrogen buses due to their lower operational costs per kilometer. The complex and expensive infrastructure needed for hydrogen fueling, coupled with reliability concerns, have limited the broader deployment of hydrogen buses.
Despite ongoing projects focusing on green hydrogen production and refueling infrastructure across Germany, battery-electric technology currently dominates local public transport in cities such as Wiesbaden, Darmstadt, Kassel, Offenbach, and Fulda, with hydrogen buses being less common and mostly confined to a few districts.
